Based on an earthquake insurance experience, the relationship between seismic ground motion intensity and the damage ratio of wooden houses is examined. In addition, vulnerability functions are evaluated from numerical simulations, in which houses are modeled with engineering judgment based on the experts’ discussion as well as statistics of the insurance experience. The vulnerability functions have a ground motion intensity index as an explanatory variable, which are defined according to construction year and degree of loss to be covered in earthquake insurance, so as to reflect that ground motion frequency which is more correlated with damage ratio is different by structural characteristics of houses and degree of loss.
